Background: Since the low concentration and short-time treatment with sodium nitroprusside (SNP), a nitric oxide (NO)–donor, cause no harm to rat bone marrow mesenchymal stem cells (MSCs), we studied the impact of SNP on MSCs differentiation. Methods: MSCs were treated with 100 and 1000 µM of SNP for 1 hour in every 48 hours and after 5, 10, 15, and 21 days in osteogenic media. The viability an...

Polyvinylidene fluoride/polyvinylpyrrolidone (PVDF/PVP) hollow fiber membranes were fabricated by dry-jet wet-spinning process. The correlated effects of the air gap length and PVP concentration ((1) the air gap length effect at the low and high PVP concentration in the dope solutions, as well as (2) the effect of the PVP concentration at the same air gap length) on the cross-section structure ...
